I'm sorry for re-submitting the fixes to frequently. I'll give it more
time in future.

It wasn't my intention to out-source testing to the patchwork bot.
I do run checks as recommended locally, which includes checkpatch.pl,
build and run-time testing. And though in this case an unneeded export
of a function was also indicated by my local compiler, I must have
missed it in the output of the kernel build. I will try to improve my
workflow in such a way that it will be less likely to miss new compiler
warnings.
